You should be able to get a variety of speakers that will fit with no issues. If that one alone is blown out, might as well replace the both sides, I've never seen any shops sell one door speaker! I run Infinity reference series, since I didn't want to modify my door and the Kappa series(which I REALLY wanted) wouldn't fit with the magnets and big tweeters. You shouldn't have trouble finding a set of speakers that fit well. The ones I got have separate tweeters, which fit fine in the factory tweeter locations. I got better sound, without any visual changes
hi most shop's know what will fit.
but i would take the speaker with you, so you don't go back to the store because if a issue.
you can match it up. and make sure of it's watts. so you don't go under or over to much.
look up what you are running to those speakers 25watts, 50 watts
most say min. 5 to 50 watts, etc.
